FAQs

Variation allows some individuals in a population to survive better in changing environments. Over time, natural selection favors individuals with advantageous traits, leading to evolutionary changes in the population.

In asexual reproduction, variations are minimal and occur due to occasional mutations during DNA replication. In sexual reproduction, variations are more significant because the offspring inherit genetic material from two parents, resulting in genetic diversity.

Mutations introduce variations in the genetic material of organisms. While most mutations are neutral or harmful, some may provide an advantage that helps the organism adapt to its environment, leading to evolutionary changes.

Organisms don’t create exact copies due to small variations that occur during DNA replication. These variations are a result of mutations that introduce slight differences between parent and offspring.
